Abstract
Techniques of positron microscopy have recently been developed for probing solids. Imaging in the prototype positron reemission microscopes was based on electrostatic focussing systems. We are now considering a different design based on a superconducting magnet and a magnetically guided positron beam, in which reemitted positrons or electrons from a sample placed in a strong magnetic field region are magnified by the divergent magnetic field. This technique does not require multiple remoderation of the positrons and should be practical with a benchtop beam. It has excellent energy resolving capability for spectroscopic study of the reemitted particles. We will discuss the possible applications of this setup toward positron reemission spectromicroscopy, as well as positron annihilation-induced Auger electron microscopy. It is also possible to utilize the same method for achieving a magnetically guilded positron microbeam for studying inhomogeneous or small samples.
